Customer Q&A with Product Specialists

Steve G. asked:
I am planning to install a wood fireplace insert in an existing fireplace. The chimney is 12-15 ft tall. Can I use a coaxial chimney liner for a fresh air intake?

For a wood fireplace insert, a coaxial chimney liner cannot be used, as this type of venting is designed for direct vent gas fireplaces and inserts. Wood-burning fireplace inserts require a stainless steel chimney liner. If you need a fresh air intake for your wood fireplace insert, it is typically supplied by a dedicated system, often a separate flexible pipe, which can run alongside the main chimney liner or through an outside wall. We carry fresh air intake kits for wood-burning fireplace inserts, such as the Drolet 5 Inch Diameter Fresh Air Intake Kit for Wood Burning Fireplace Inserts.

John C. from Sacramento, CA asked:
I have a Montigo M36CST, two-sided gas-burning fireplace. The main burner has developed a huge hole. If I can't find a replacement for the burner, I may have to consider an insert. I was told by a local fireplace technician that there are no replacement parts available and that an insert would not work. I would like another opinion.

We are not a Montigo dealer and cannot provide parts or advise on options for your specific unit. We recommend contacting the manufacturer (www.montigo.com) or calling a local dealer for more information. We apologize for the inconvenience.
